Application filed October 18, 1904. Serial No. 228,934.

Torr/Z7 whom, it may concern.-

Be it known that I, FRANooIs DRoNNE,a citizen of the United States,residing at Annadale, in the county of Richmond and State of New York,have invented certain new and useful Improvements in Safety-Hooks, ofwhich the following is a specification such as will enable those skilledin the art to which it appertains to make and use the same.

The object of this invention is to provide an improved safetyspring-hook for use in connection with harness of various kinds andclasses, and also in connection with dog-collars or chains and forvarious other and similar purposes.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Figure 1 is a front view of my improvedsafety-hook and showing the hook closed; Fig. 2, a side view at rightangles to Fig. 1,

and Fig. 3 a section on the line 3 3 of Figs 1 and showing the hookopen.

In the practice of my invention I provide a spring-hook a, composed ofany desired metal and consisting of two side members a and (0 the latterof which is resilient. The side member a at the end thereof is projectedand formed into a cylindrical shank or body portion 6, which is longerthan the resilient side member a of the hook and which is provided atits end with a ring or eye c,the plane of which is at right angles tothat of thehook in the form of construction shown. The cylindricalbodyor shank portion 6, which is connected with the side a of the hook,is provided in the side thereof which faces the end of the resilientside member a of the hook with a longitudinal recess (Z, adapted toreceive the free end of said resilient side member of the hook, and saidend of the side member a of the hook is provided with anoutwardly-directed lug or projection 0, also adapted to enter the recess(Z, and the recess (Z is of such depth as to receive the said end of theresilient portion t of the side member a of the hook is a collar or bandf, which is free to slide on said cylindrical shank or body portion 6and to be moved longitudinally thereof, and when the hook is not in usethe collar or band f rests in a position adjacent to the ring or eye 0,as shown in Fig. 3, and when it is desired to use the hook or to lockthe resilient side member a for use the said resilient side member ispressed down so that the end thereof and the lug or projection a will bereceived by the recess (Z, and the collar or band f is moved over thesaid-end of the resilient side member a of the hook into the positionshown in Figs. 1 and 2, and said collar or band 7 is engaged by the lugor projection e, and the hook is locked in the closed position, theresilient side member a springing outwardly,as shown in Fig. 2,so thatthe lug or projection 6 will engage the band f. In order to open thehook, the resilient side member is forced inwardly and the collar orband f moved outwardly in the direction of the ring or eye 0, thisposition of the parts being shown in Fig. 3.

In the construction shown the hook member a is loop-shaped or U-shapedin form; but said hook member may be of any desired shape, and all theparts of this device may be made of any preferred dimensions, and maytherefore be made of any desired strength.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is
